1.Application
The long welding neck flange is mainly applied to the construction of pressure vessel functioning as a nozzle (such as a thermowell nozzle). To attach a common welding neck flange to a pressure vessel, a piece of pipe is required with additional welding. A LWN flange on the other hand attaches directly to the vessel, hence, it can be viewed as an integrally reinforced nozzle. It avoids making a weld seam at pipe to flange and provides self-reinforcement.
2.Weight Calculation
The weight of a long welding neck flange can be calculated by using the following equation: Mass = [ ( X + B ) / 2 * ( X – B ) / 2 * 0.0246615 * ( Y – T ) * 10-3 ] + [ ( D2 – B2 – nd2 ) * T + ( G2 – B2 ) * t ] * 6.165375 * 10-6, Assume that the flange is made of carbon steel.
3.Material Specification of B2 Hastelloy Flange
| UNS: | N10665 |
| Specifications: | ASTM B564/ASME SB564 |
This nickel basedAlloy B2 RTJ Flangecould be used in an as-welded condition as it hinders the formation of grain-boundary carbide precipitates that could occur while welding in the heat-affected weld area.
Hastelloy B2/ B3 Flangesalso offers excellent resistance to localized attack, for instance, pitting, corrosion, and stress related corrosion cracking as well.
4.What is a Long Weld Neck Flange?
Long Weld Neck Flanges are like weld neck flanges, except for the neck, which is extended and acts like a boring extension. Long weld neck flanges can be used in high pressure industrial applications, as well as high temperature situations. They are often utilized in the oil and gas or petrochemical industries.
